A changeover-to-backup technique in a computer system which allows a terminal to switch from a main management system to a back-up system, but prevents the terminal from doing so in the case of a temporary fault or minor problem negligible enough not to be treated as a fault. A terminal 21 transmits a registration request (S101) to a backup system 1b, if a fault occurs in a main system 1a, but the backup system 1b is prevented from providing a management service till a startup request (S204) made by a monitoring server 18b is received. The technique is applicable particularly to call centres in which the management system routes telephone calls to operator terminals. |
